BACKGROUND: Immune checkpoint blockade (ICB) is rapidly becoming a standard of care in the treatment of many cancer types. However, the subset of patients who respond to this type of therapy is limited. Another way to promote antitumoral immunity is the use of immunostimulatory molecules, such as cytokines or T ... More
Mammalian cell penetration, siRNA transfection, and DNA transfection by supercharged proteins.
Authors:McNaughton BR, Cronican JJ, Thompson DB, Liu DR,
Journal:Proc Natl Acad Sci U S A
PubMed ID:19307578
'Nucleic acid reagents, including small interfering RNA (siRNA) and plasmid DNA, are important tools for the study of mammalian cells and are promising starting points for the development of new therapeutic agents. Realizing their full potential, however, requires nucleic acid delivery reagents that are simple to prepare, effective across many ... More
Amino acid residues critical for endoplasmic reticulum export and trafficking of platelet-activating factor receptor.
Authors:Hirota N, Yasuda D, Hashidate T, Yamamoto T, Yamaguchi S, Nagamune T, Nagase T, Shimizu T, Nakamura M,
Journal:J Biol Chem
PubMed ID:20007715
'Several residues are conserved in the transmembrane domains (TMs) of G-protein coupled receptors. Here we demonstrate that a conserved proline, Pro(247), in TM6 of platelet-activating factor receptor (PAFR) is required for endoplasmic reticulum (ER) export and trafficking after agonist-induced internalization. Alanine-substituted mutants of the conserved residues of PAFRs, including P247A, ... More
Caveolin regulates endocytosis of the muscle repair protein, dysferlin.
Authors:Hernández-Deviez DJ, Howes MT, Laval SH, Bushby K, Hancock JF, Parton RG,
Journal:J Biol Chem
PubMed ID:18096699
'Dysferlin and Caveolin-3 are plasma membrane proteins associated with muscular dystrophy. Patients with mutations in the CAV3 gene show dysferlin mislocalization in muscle cells. By utilizing caveolin-null cells, expression of caveolin mutants, and different mutants of dysferlin, we have dissected the site of action of caveolin with respect to dysferlin ... More
Functional analysis of FSP27 protein regions for lipid droplet localization, caspase-dependent apoptosis, and dimerization with CIDEA.
Authors:Liu K, Zhou S, Kim JY, Tillison K, Majors D, Rearick D, Lee JH, Fernandez-Boyanapalli RF, Barricklow K, Houston MS, Smas CM,
Journal:Am J Physiol Endocrinol Metab
PubMed ID:19843876
'The adipocyte-specific protein FSP27, also known as CIDEC, is one of three cell death-inducing DFF45-like effector (CIDE) proteins. The first known function for CIDEs was promotion of apoptosis upon ectopic expression in mammalian cells. Recent studies in endogenous settings demonstrated key roles for CIDEs in energy metabolism. FSP27 is a ... More
